【摘要】 以道路交通安全为出发点,通过对现行的道路几何设计参数的分析,以生理-心理学为依据,利用动态心电仪检测,把大量实测数据借助计算机进行处理分析,得到平曲线半径的阈值并且进行了验证．在此基础上结合我国国情提出了人性化的双车道公路线形设计的新的研究方法,从而为减少交通事故的发生找到了一条新的途径,为从驾驶员舒适性方面修订我国山区双车道公路线路设计规范提供了理论依据．更多还原

【Abstract】 This study analyses the current horizontal curve design parameter based on psychology and physiologic theories, the experimental data is measured by using advanced physiological signal measurement apparatus as they drive on a two-lane highway in a mountain area, and then the reasonable thresholds of horizontal curves radius are obtained and verified using experimental data in this study. The thresholds realize the human design and decrease traffic accidents, which reflect the psycho-physiological characters of the drivers on two-lane highway in the mountain area.更多还原
